Question:

I have a 2021 Coachmen Leprechaun Premier based on the E-1450 Super Duty chassis that came with the Firestone Ride-Rite air bag option. One of the air bags is leaking and I am trying to find the replacement model number. Info on your site only lists 2020 and 2022 model years. Can you please help?

Hey Jim, thanks for reaching out. We do list one Firestone Ride Rite kit for the 2021 Ford E-450, the Firestone # F22ZR. If this is what you have, the correct replacement air bag would be part # F6397.

Generally we like to get the part number from your air bag to confirm fitment. There should be a sticker on top of the bag that says this. If you can't get to the sticker you will at least want to compare the dimensions to be sure you are getting the right thing. The # F6397 air bag is 8.3" tall when extended, and it is 6.6" in diameter.

If you need something different just reply below and let me know. I will get back to you.

Hey Jim, did the replacement air bag with the same dimensions as the Firestone Ride-Rite kit end up matching your setup on the Leprechaun? Your update could make it easier for others trying to confirm the right fit for their E-450 chassis.
